HAY BAKE AND T'DDER.

Specification of Letters Patent. I patqgntgd Sgptgg, 1913.

Application led April 11, 1911. Serial No. 620,420.

To all 'whom t may concern.:

B e itknown that I, LEWIS E.` WATERMAN, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented 'certain new and useful Improvements in Hay Rakes andTedders, of which the following is a specification.

The object of this invention is to constructa .side delivery rake, whichcan withi out changing the machine, be converted into a hay tedder bysimply rotating the teeth in the opposite direction.

The further Object of this invention is to support the rear portion 'ofthe rake upon two wheels with an equalizing device between them so thatthe vertical movement thereof is one-half that of a ralesupported upon asingle wheel. 'p

In the accompanying drawings Figure 1 is a plan view. Fig. 2 is asection on'dotted line g, g, Fig. 1. Fig. 3 is a section on dotted line(Z Z Fig. l. Fig. 4 is a section on dotted line a a Fig. 1. -Fig. 5 is ahorizontal section through the front supporting wheels and the bearingof the `tranne, also the gear drive connection with the rake head. Fig.6 is a vertical section on dott-ed line c e Fig. 5. Fig. 7 is a sectionon dotted line o o Fig. l. Fig. 8 is a section on dotted line f f Fig.7. 'Fig 9 is a section on dotted line c o Fig. 1.

rIfhe axle l is supported by the wheels 2 and 3 and the usual clutch 4shown at Fig. G is employed to connect the wheels with the axle. A.sleeve 5 is supported by the axle and two bearings t and 7 areconnectedrto the sleeve by the U bolts S. A bevel gear 9 is connected toa sleeve 10 which is connected to the axle 1 by the set screw 11. Abevel pinion 12 sleeve 10. l From the bearing 6 extends 7vertically atoothed quadrant 13, and a hand lever 14 is pivotally connected to thebearing and its dog en'gages;the toothed quadrant. Two collars 1,5 arepinned to the axle and between these collars is'located a clasp l6towhich a link 17 is connected, and the other endl of this link isconnected to the hand lever 14. By means ot' the hand lever 14 thesleeve 5 can be moved lengthwise on the axle 1 which will carry 'thebea-rings 6 and 7 withit. A bar 18 is pivotally lsupported by theforward portions of the bear:

is also connected-to the;

position by pins 4Q.

, ings Gand 7, and to this bar is connected ai tongue 19. Braces '20connect with the tongue also with the bar 18. A seat 21 is supported bythe tongue, and'a draft connection 22 is also connected to the tongue.vThe bearing 7 has a rearward extension 23 which supports the hub 24ofa" bevel pinion A rectangular .trarne com? prises the side bars 2G and:27 and the endbars 28 and 29. i

' A square hollow Yshaft 30 has one end located in the hub 24 of thegear 25, and `its other end is located in a bracketl. depending from theundert'ace of the end bar Q9 of the rectangular frame. Arms 82 extendfrom the bearing 7 and are connected to the underiace of the end barrectangular frame. AA square bar 33 has one end connected to the bearing6 and'its other end is connected to a bracket 34 selcured to the sidebar 27 of the rectangular frame near its rear'portion.

A brace trod 85 extends diagonally of the rectangular trame and its endsconnectedY thereto and its center portion is connected 80 to the bar bythe bracket 36, and straps 37 connect the bar 33 and the side bar 26 ofthe rectangular traine. To the bar 27 of the rectangular fra-nie aresecured two brackets 3411- and cach provided with an vupwardly extendingtubular section 35.3. A brace barSGlconncctsone of the sections with thebar,33 and a bracebar connects the other section with the side .bar'26et' the rectangular frame.- These brace'bars 90 serve to hold thetubular extensions in a {fertical position.

lower. end 4of which is connected-a caster wheel 39. Around theupperportions of each ot' the 4shatts 38 is loosely mounted collar 4),and these collars areconnected by double bars 41. The coll'arsare heldin To the bracket 34 is'f pivoted a bell-crank 43 and to' one arm ofthis bell-crankis pivoted an upright .bar 44 In each vof the tubular.'`sections is located a shaft 38 tothe the upper end of which is locatedbetween l the bars 41 and pivotally connected thereto.

TQ, the other arm of this bell-'crank is piv z oted `a Irod whichextends tothe forward portion of the rake,` and-is connected to ahand-lever 46. A toothed segment 47 is supported by the bar 33 and thebearing-6;

T .e hand lever`46' has a pivotal connection with the segment 47 and isprovided with les . nu@ rig. r.

the usual dog-and. thumb lever engagement with the toothed segment. Bymeans of this hand leverI 46 the bell-crank 48 'may be rocked which willraise or lower the rear portion of the rectangular frame by sliding thetubular sections 35%L on the shafts 88.

By the employment of the two wheels 39 and the bars 4l in theirconnection with the upright bar 44 each wheel in passing over anobstruction will raise. the rear portion of the rect-angular frame onlyone half the .distance it would if it was connected directly to theframe thereby allowing the rake teeth to more nearly contact with theground at all tunes.

To the hub`24 isI connectedV a casing 48 by the set screw 49, and thishub is connected to the square shaft 30 by the bolt 50. To the other endof this square shaft 30 is secured a .three armed spider 51 by the setscrew 52.

Three shafts 53 are mounted in the spider arms 51 and in the casing 48so as to turn therein, and to each shaft 58 are secured spring teeth 54.To each of the shafts 53 is pinned an eccentric elliptical spur gearIntermediate eccentric elliptical spur gears 56 are mounted on the studs57 supported by the casing 48 and mesh with the eccentric rellipticalspur gear 55. A .spur gear 58 is.

- formed either integrallygwith the eccentric elliptical gear 56 orconnected to revolve with it on the stud 57. A spur gear 5S) is looselymounted on the hub 24 and toI the hub 5f this gear is connected a handlever (30 which is provided with a thumb latch and dog engagementI witha toothed segment 61 secured to the end bar 2S of the rectangular frame.This spur gear 59 meshes with the spur gears `When the .bevel gear lisin mesh with thebevel pinion 25, the shaft 30 and the spider 5l andcasing 48 connected to it will be rotated in the direction indicated bythe arrow' on Fig. i). This rotation of the spider and casing will causethe gears to be oscillated through their gear connection with thestationary center gear 59. These rotations and oscillations will impartmovements to the teeth 54 in apath indicated bythe dotted line Fig. 9,vand in the central dotted By forming the gears and 56 elliptical and"eccentric, the teeth 54 do not stand in a vertifealposition throughouttheir movements, but have a swinging movement as indicated in`A` dottedlines Fig. 9.

This swinging movement tends to lift the hay and roll it along into awindrow instead of bodily pushing it, which it does when the teeth standvertically, and by swinging the teeth a greater range of movement is hadthereby increasing the distance.theteeth remain or practically remainnear the ground. By moving the hand lever to the right hand facing thelever, the teeth willtravel in a path shown by the dotted line 62 inFig. 7,'

and when the hand lever is in a vertical or normal position, the teethwill travel in the path indicated by the dot-ted line 63 .Fig 7 'I hestrippers 64 serve to shed the hay from the teeth and prevent the haybeing carried over the teeth.

By means of the hand lever 14 the forward end of the frame is shifted sothe bevel gear 9 may be placed in mesh with the bevel pinion 25, and indrawing the machine over the field the rake teeth will be moved in theopposite direction thereby producing a hay7 tedder. The gear 9 beinglarger than the gear l2, the shaft 30 will be rotated faster when themachine is used as a hay tedder.

By means of the hand lever 60 and its enl gagement with thetoothedsegment 61, the gear 59 is rocked which will rock the gears 55, therebylocating the teeth 54 either ahead or in rear of the center position asshown'in solid and dotted lines `Fig. 7. The changing of the relation ofthe teeth to the ground will carry the hay farther forward when used asa hay rake, and will, when used as a hay tedder carry the hay farther tothe rear.

I claim as my invention.
